Actually my comment was in reference to Insure++ not C++Test. Insure 7.5 will not install on x64 window 10. I get "The System PATH environment variable could not be set, because \HLKM\SYSTEM\CurrentControlSet\Control\Session Manager\Environment\PATH could not be parsed" during instrumentation of libraries. I then get a message that Insure++ cound not complete, because Microsof Visual C++ is not install. Followed by VSIX Installer failure (log attached).

UPDATE
We will be shipping a new release of Insure++ supporting Windows 10, very shortly, (It's currently in our final QA process). After that, the next version of Insure++ will support VS 2017. We currently have a target date of 30-Sep-2018.
